（24点算法）第一个算法是用C语言描述的，第二个是C++描述的，都是我在网上搜集整理的计算24点的算法，其中第二个最容易理解（递归的魅力），因为它用了string这种很方便的字符串流，第一种算法很复杂，我每次都要再看过，大家可以收藏起来慢慢品味~
,(24-point algorithm) algorithm is first described by C language, the second is C++ are described, all my online collection of 24 points, finishing the calculation of the algorithm, in which the second most easy to understand (the charm of Recursive) because it is a string with the string that flow easily, the first algorithm is very complex, every time I re-read, we can taste away slowly ~
